Red+Blue=Purple
The object will appear to be blue. However, the object would be indistinguishable from an object that reflects all colors of light. If yellow light were shone on an object that reflects only blue wavelengths, the object would appear to be black.
A blue object will absorb most light except blue wavelengths of light, which it will reflect, making the object appear blue. This is because objects appear a certain color based on the wavelengths of light they reflect.
A blue object appears blue because it absorbs most colors and reflects blue light. However, when a red light shines on a blue object, the blue object would absorb the red light and reflect blue, so it would still appear blue.
A blue object appears black when illuminated with light because it absorbs most of the light that hits it, including the blue light that gives it its color. This absorption of light prevents the object from reflecting enough light to appear blue, making it appear black instead.
a blue object reflects blue it absorbs the rest of the colors
Black, because the blue light would be absorbed into the object's pigment and as there is no green light to reflect, the object would appear black.

will appear black
The green object will appear black because it will not reflect any of the blue light shone on it. Green objects primarily absorb blue light, so without any green or red light present, the object will appear dark.
In blue light, a yellow object would appear dark or black because yellow absorbs blue light and reflects other colors. This means that the object wouldn't reflect any of the blue light, making it appear dark.
When white light shines on a blue object, the object absorbs all colors except blue, which it reflects. Our eyes perceive the reflected blue light, making the object appear blue to us. This happens because different colors of light have different wavelengths, and blue wavelengths are reflected while others are absorbed.
